LiquidSonics’ Seventh Heaven Professional is dedicated to the reproduction of the most sought after hardware reverberation tool of a generation – the Bricasti M7. By combining the realism of Fusion-IR with an extensive multi-sampling of the legendary hardware reverb, Seventh Heaven Professional truly redefines contemporary producers’ expectations of any native software reverb plug-in.

The Next Generation of Native Reverb

The best software recreations of classic hardware capture not only the sound – they capture the experience. They blend reproduction with reimagination. Seventh Heaven Professional’s advanced digital signal processing techniques intertwine with controls that closely mirror those of the M7 presenting the freedom of an algorithmic reverb with the breathtaking clarity and authenticity of a Fusion-IR reverb.

Production techniques that were previously impossible with a convolution reverb can be accomplished with ease. Now you can experience the power to change reverb early reflection patterns, decay times, delays, and the tone of the roll-off filters just as thousands of leading producers do on the actual M7 hardware. All in a beautiful, modern and immediately approachable graphical interface. See and hear more for yourself in the video and audio clips.

Seventh Heaven Professional provides arbitrary reverb decay times from 200 ms up to 30 seconds for every preset and includes multi-band decay length multipliers – an unprecedented feat particularly for modulated convolution reverbs.

The decay time challenge

A convolution reverb will typically be able to window a decay time with envelopes of varying complexity, apply pitch/stretch control, and some even allow rudimentary multi-band length modification. However factors such as simulated room size, low frequency response and diffusion/density should be linked to decay time so traditional controls considerably compromise acoustic authenticity.

The solution

Seventh Heaven Professional solves such problems through extensive multi-sampling and intelligent interpolation algorithms. Judicious use of advanced data selection techniques and lossless compression technologies result in a similar disk space requirement to that of the original M7 Fusion-IRs.

Multi-band decay provision

Many algorithmic reverbs provide the ability to extend or contract the reverb decay in low and high frequency bands. This is crucial for the accurate simulation of many acoustic spaces. Seventh Heaven Professional is able to reproduce a similar effect using supplementary multi-band filtering of independently generated reverb decay curves.

The M7 provides two distinct frequency roll-off controls, one for the early reflections and one for the late reverb. These have an enormous impact on the character of the reverb taking it from bright and shimmering to deep and dark.

Typically when an M7 preset is sampled these filter positions are fixed and cannot later be modified. This hugely limits scope when mixing if the early reflections or late reverb needs brightening. A basic roll-off, bell or shelf filter can be useful for reducing spectral content if an inauthentic filter curve shape is acceptable, but is incapable of providing additional spectral content beyond that originally sampled.

Seventh Heaven Professional provides authentic and full control over these two key parameters in either direction. Every filter position available on the hardware can be selected, brightening or darkening the reverb just it would do with the hardware. This truly redefines the boundaries of possibility in a sampled reverb making it suitable for even the most demanding of professional producers.

Depending on the algorithm version the preset is originally taken from (either M7 algorithm v1 or v2) a shallow (for v2) or steep (for v1) filter curve is used for the late reverb component. These filters have been accurately modelled on the M7’s filter model curves.

In a typical mix one rarely perceives reverb once it decays to 20 dB below the onset level so a high quality early reflection engine is of particular importance. The M7 provides numerous early reflection patterns specifically designed to avoid the phasing and other acoustically undesirable effects experienced in many reverb early reflection modules. Those based on simple reflection models (often implemented as discrete delays) are highly susceptible to phasing and balance problems such as those caused by the Haas precedent effect.

The M7’s early reflections are suitable for any space from small rooms to very large cathedrals, and even work well with plate simulation. When combined with the reflection roll-off and early/late mix controls very convincing early stage reverb can be accomplished.

Each of these reflection patterns has been individually sampled and can be selected for use in any of the presets in Seventh Heaven Professional allowing true freedom in early stage of a reverb’s composition.

The relative balance of the early reflections and late reverberant field are of particular importance in any simulated acoustic space or device. Full control over these can be achieved with Seventh Heaven Professional.

The Bricasti M7 is notable for its special consideration of modulated low frequency reverb behaviour (200 Hz and below) independent of the algorithms governing early reflections and the late reverb. This frequency area is crucial to the accurate reproduction of many spaces, and accurate control of it is of great importance to many producers. The Reverberate 2’s Fusion-IR sets allow control over the early and late reverb components, but Seventh Heaven Professional goes much further in providing more precise access to the level of all three reverb components.

The pre-delay and delay modules are fully customisable in Seventh Heaven Professional and respond in a manner true to the original hardware.

Pre-delay

The M7’s pre-delay control does not delay the entire reverb signal, so typical attempts to modify a sampled M7 pre-delay will not produce authentic or usually even desirable results. Modification of the hardware’s pre-delay only affects the very low frequency reverb and the late reverb, the early reflections stay close to the dry signal. For the first time this behaviour is faithfully reproduced providing much more control over any inherent pre-delays in presets or the addition of pre-delay in the very natural style of the original hardware.

Delay

The M7’s delay feature feeds a modulated multi-voice dry signal back into the late reverb processor’s signal chain. In Seventh Heaven Professional multiple variants of the preset are sampled: those with the original modulated multi-voice delay and others without. This enables very convincing addition, removal or modification of delays using a traditional single-voiced feedback delay which sounds very close to that of the original hardware. This added flexibility means that presets sampled with a delay which does not quite fit with tempo of a song can be modified in very musical ways.

Tempo synchronisation

The delay and pre-delay can be set to synchronise to the host’s tempo using half, dotted and regular 1/32 to 1/4 notes.

The M7’s ultra-realistic v1 algorithm and its heavily modulated v2 algorithm are perfectly complimented by its implementation of a classic British non-linear reverb algorithm.

Instantly recognisable from numerous vocal and drum tracks from the 80s, the non-linear reverb has a characteristic sustained reverb region before decaying away very naturally. It is the perfect way to complete Seventh Heaven Professional capabilities, and even includes features not found on the original hardware such as the ability to mix in the very low frequency reverb component and specify a reverb delay to boost and thicken the sound.

The revolutionary capabilities of Seventh Heaven Professional have been achieved though meticulous multi-sampling and characterisation of the Bricasti M7. Tens of thousands of pristine captures are combined intelligently to very closely match the sound of the original hardware. Never before has this level of detail been possible in a convolution based product, and no other algorithmic reverb approaches the finesse of the Bricasti M7. LiquidSonics is proud to present a defining landmark in native reverb capability.

Reviews

Sound on Sound

“If you want a lush chamber for an exposed solo vocal, or a discreet hall to add class to a slightly dry classical recording, or an ambience to help a close-miked drum kit breathe, this is pretty much without peer. Seventh Heaven Professional is simplicity itself to use, sounds great, and offers more than enough editing flexibility for normal use.”

“With enough time and effort, you can coax a good sound out of most reverbs, but what sets products like Seventh Heaven apart is that it’s impossible to get a bad sound from it.”

Resolution Magazine

“The plug-in has an incredibly professional sound and seems to impart a nice sheen to most sources. In comparison to the actual M7 there are some slight tonal differences but it does a very respectable job of supplying those expensive sounding reverbs.”

“The only drawback of the free trial is that if you try it … you will probably want it!”

Audio Producer News

“Seventh Heaven is shockingly good. So good, in fact, that I almost don’t want to use any other reverb on vocals after hearing it. It’s complex, lush, silky and unobtrusive.”

“This reverb literally makes me want to buy a real M7. It is so addictive when being fed through multiple sends because you don’t get caught in a tidal wave of frequency build-up. The sound is so clarified and this is due to the fact that the source unit didn’t have the level of unwanted coloration suffered by normal algorithmic reverbs.”

“I found myself regularly reaching for the VLF (or Very Low Frequency) control. This imbues so much character into the sound that it is a must on good vocal performances.”

Computer Music Magazine

“Like that of the M7, Seventh Heaven’s library of halls, chambers plates and spaces is simply breathtaking in its scope and quality, with that famously organic Bricasti density, clarity and ER cohesion.”

“Seventh Heaven Professional nails the Bricasti sound and vibe in a convolution plugin that feels amazingly algorithmic.”

“Like the M7, Seventh Heaven often just works with minimal or no user input.”

Rating: 9/10

Audiofanzine

“Seventh Heaven Professional is extremely user-friendly. To the point that’s is easy to forget that it’s a convolution reverb! No, seriously, the versatility and effectiveness of the plug-in categorically do away with the hitherto borderline between algorithmic and convolution reverbs.”

“As far as I’m concerned, it gets the highest rating possible and the Best Product Award. It’s been almost five years since I started writing reviews for Audiofanzine and I think it’s the first time I’ve ever given such a rating, but I have no doubts about it because Seventh Heaven Professional is hands down the best software reverb available today.”

AskAudio

“Seventh Heaven Professional is truly angelic and sponges that ethereality on to pretty much everything it touches. Because it does allow you to pump up the bass, it’s a great tool for doubling and intensifying kick drums, bass and more, while still making your vocals, guitar and whatever else you throw in to it sound holy.”
